RU2501305C1 - Method of feeding young stock of farm animals - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture and can be used in the fattening of young stock in mountain pastures. The animals are fed with green fodder from pastures fertilised with CMF (complex microbial fertiliser) at a dose of 500 kg/ha once in 2-3 years at an annual foliar dressing with 0.1% aqueous solution of Extrasole at a rate of 200 g/l at regrowth of grasses. All the period of fattening, 1.0-1.5 ml per 1 litre of water is added to drinking water of animals.

EFFECT: weight gain of young stock is increased.

Description

The invention relates to agriculture, in particular to livestock.

A known method of feeding calves, including adding to the normal diet a complex of salts of microelements (Microelements in animal husbandry in the Central Ciscaucasia. ID Tmenov. Ordzhonikidze: Publishing House "IR" 1973. P.102-104).

However, with such feeding, the preparation and storage of solutions presents certain inconveniences; not all trace elements are readily available.

A known method of feeding farm animals (RF patent No. 2236147, publ. September 20, 2004, IPC A23K 1/00, A23K 1/06), which includes the use of biosporin probiotic as a feed additive to the main diet of waste, production in liquid form once a day.

A known method of feeding farm animals (RF patent 2270579, IPC A23K 1/16, published on 27.02.2006 g), including the use of biologically active feed additives "Pihteks". However, in the known methods, biologically active preparations are used only when added to drink or feed and are not used when growing herbs on hayfields and pastures.

The technical result is an increase in weight gain, expanding the range of feed additives.

The technical solution of the claimed object lies in the fact that fattening of young cattle during the grazing period (six months) is carried out using freshly cut green mass from the pastures of fertilized KMU (complex microbiological fertilizer) at a dose of 500 kg / ha once every two to three years and annual foliar treatments with the biological product "Extrasol" in the norm of 200 l / ha of 0.1% aqueous solution. Additionally, a solution of Extrasol is added to drinking water in an amount of 1.0-1.5 ml per 1 liter of water.

The method is as follows.

Once every two to three years, CMU in the norm of 500 kg / ha is applied to the pasture in a scattering manner in early spring before the start of the plant vegetation. CMU is a granular complex fertilizer containing a set of macro- and microelements and active forms of microorganisms that provide nitrogen fixation, mobilization of soil compounds of phosphorus, potassium and other elements inaccessible to plants, promotes plant survival in conditions of nutrient deficiency.

CMU was developed by Bisolbi-Inter LLC, St. Petersburg (RF patent No. 2318784).

At the beginning of the growth of perennial grasses on the pasture, foliar top dressing with a 0.1% aqueous solution of Extrasol is carried out at a rate of 200 l / ha and is repeated in the phase of active growth, as well as when growing after each mowing.

The whole period of feeding, animals are fed grass cut from fertilized pastures and extrasol is added to drinking water at a dose of 1.0-2.0 ml per 1 liter of water. Extrasol is a liquid form of complex action microbiological fertilizer based on the rhizospheric bacteria Bacillus Subtilis Ch 13, developed by the GNU All-Russian Research Institute of Agriculture of Microbiology, St. Petersburg. The addition of Extrasol in drinking for animals contributes to the enzymatic activity of the rumen and to the better assimilation of the nutrients of the pasture feed, which positively affects the increase in live weight. An example implementation.

Early in the spring, CMU was scattered in the pasture at the rate of 500 kg / ha, and at the beginning of the growth of grasses, they were treated with an aqueous solution of Extrasol at the rate of 2 l per 200 l / ha. In the phase of active growth, repeated foliar treatment of the pasture with Extrasol solution was carried out.

After the first and second mowing, when growing herbs, foliar feeding of Extrasol solution was repeated in the same norm.

Green pasture feed was assigned to four groups (three heads) of 6-7 month old gobies in sufficient quantity against the background of the necessary feeding with concentrated feed from different parts of the pasture: from non-fertilized; fertilized CMU; treated only with Extrasol; fertilized CMU and treated with Extrasol.

The entire feeding period for three more experimental groups of animals was daily added to drinking water Extrasol in an amount of 1.0; 1.5; 2.0 ml per 1 liter of water on the background of feeding herbs from a plot of fertilized KMU with foliar treatments with Extrasol.

The control group received food and drink from an un fertilized pasture site.

The results of the experiment are shown in the table.

The best option - feeding green feed from fertilized KMU and extrasol (extra root treatment) to the pasture area and the additional introduction of extrasol at a dose of 1.0-1.5 ml per 1 liter of drinking water provided an experimental gain of one animal per head up to 12.8%, which amounted to 4460 rubles in monetary terms. A further increase in the dose of extrasol in drinking water is not advisable, because does not improve the studied indicators.
